Early Pregnancy Symptoms

Kate • 33. Canadian. TTC #1 since Aug. 2014. PCOS. MC in June 2016. Uterine septum and ovarian cyst removed January 2017. Started Metformin January 2018.
I know the typical signs of early pregnancy, but had anyone experienced a gurgling stomach. I don't really know how else to describe it. My stomach is bloated and sore, and every few minutes it gurgles! Is is completely unrelated?
